A skill is a folder of instructions mounted into the agent's run. Give a job one or more with `--skills`; every arm gets them. ```bash theme={null} evolve run \ -d terminal-bench-4@4.0 \ -a claude \ -m fable \ --skills skills.sh/acme/skills/pdf \ -l 5 \ --watch ``` `--skills` (also spelled `--skill`) repeats, and accepts: * `skills.sh//[/]` * `org/repo[@ref]` * an https git URL * `upload:`, a skill you uploaded * `name:`, your moving name pointer, resolved on the server to its current upload * a local folder, which is uploaded first and then referenced ## Upload a skill ```bash theme={null} evolve skill upload ./my-skill evolve skill list evolve skill show name:my-skill evolve skill delete ``` The folder's name becomes your moving name pointer: `name:my-skill` resolves to the latest upload with that name, and an unknown name is refused with `skill_name_not_found`. `skill show` prints the metadata and the `SKILL.md`. A skill that a running job references cannot be deleted, and past jobs keep the version they ran with. The job's arm records what mounted under `skill_locks`: name, pinned source, digest and, for a git skill, the repository and commit. A skill that cannot be fetched fails the trial as an infrastructure error, never as a score. Every flag of `evolve skill`.
